Randy you may not get any more higher peak but make it broader. I cheated on the guess. I went to your file on the dyno and and about what it may pick up. I have seen where ther was only 10 hp increase but the power band was now so broad that it was a monster. So dont be too dissapoint if it dosent make alot more peak,but hopefully more alaround power!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
